This tunnel was built at a depth of 35 feet, being 4 feet high and 3 feet wide. It is supposed that it was planned by engineers and architects. On its southern end, in Tijuana, the tunnel was accessed by a metal stairway down at a depth of 20 meters. It was masked by a building at about 80 meters from the border fence.
